This folder includes the honeybee modules only for Grasshopper. In order to create the full library for Grasshopper you need to add these files to the core honeybee library:

1. Install honeybee library from honeybee repository.
2. Copy the files from this folder next to the files in honeybee.

You can use this library inside Grasshopper. If you want to avoid steps 1 and 2 you can also get the latest stable released library from here.
